Kona Cindercone offer?

[steve86]

Ive been offered a Kona Cindercone ive only seen a poor picture on a phone but it looks like its a red/purple colour he says its totally original and a 91 model, wondered how much this is worth and whether the colour sounds applicable to his 1991 claim?
cheers

the 91 cindercone is like a bronze colour with black project 2 forks and a suntour xc ltd groupset if that helps
